This 127 x 170mm diamond core bit offers a substantial diameter for major building services installations, large ventilation systems and significant structural penetrations in commercial and industrial settings. The 127mm size provides excellent clearance for substantial pipework, major ductwork runs and installations where future access or additional services may be required. Featuring professional-grade laser-welded diamond segments, this bit maintains consistent cutting performance throughout demanding applications in brick and concrete blocks. The 1/2" BSP threaded arbor connection ensures secure mounting on robust core drilling equipment, providing the stability essential for safe operation at larger diameters. At 170mm length, this variant offers practical drilling depth whilst keeping the tool manageable for professional tradespeople working on substantial installations.
